We often hear about the importance of the gut microbiome and skin microbiome. But there is another delicate ecosystem that plays an important role in women’s health: the vaginal microbiome.
From menstruation and pregnancy to childbirth, perimenopause and menopause, hormonal and physical changes can influence the vaginal environment over time. Some women may also notice vaginal dryness, discomfort, changes in tissue elasticity or urinary symptoms during these life stages.
Not every intimate symptom is a hygiene problem — and not every change is caused by the vaginal microbiome.
Understanding what is normal, how to care for the intimate area and when to seek medical advice is an important part of looking after your women’s health.
What Is the Vaginal Microbiome?
The vaginal microbiome refers to the community of microorganisms that naturally live within the vagina.
In many healthy women of reproductive age, this environment is predominantly supported by Lactobacillus species. These beneficial bacteria help maintain the vagina’s naturally acidic environment, which can make it more difficult for certain potentially harmful microorganisms to overgrow.
However, this balance is not completely static.
Your vaginal microbiome and vaginal pH can naturally change throughout life due to factors such as:
- Hormonal changes
- Menstruation
- Pregnancy and breastfeeding
- Antibiotic use
- Sexual activity
- Perimenopause and menopause
Importantly, the vagina is designed to maintain and cleanse its own internal environment. Trying to make it “extra clean” can sometimes cause more irritation rather than improve vaginal health.
What Can Affect Your Vaginal Microbiome?
Several everyday and hormonal factors can influence the vaginal environment.
Hormonal Changes
Oestrogen plays an important role in supporting vaginal tissue and an environment in which Lactobacillus bacteria can thrive.
Changes in oestrogen during the menstrual cycle, pregnancy, breastfeeding, perimenopause and menopause may therefore affect both vaginal tissue and the microbiome.
Antibiotics
Antibiotics are sometimes necessary for treating bacterial infections, but they may also affect beneficial bacteria.
Some women notice changes in vaginal discharge or develop vaginal symptoms during or after a course of antibiotics.
If symptoms persist, speak with a doctor rather than trying to correct them through repeated cleansing.
Douching and Over-Cleansing
The inside of the vagina does not need to be washed with soap, antiseptics or feminine cleansing products.
Douching can disturb the natural vaginal environment, while strong soaps, perfumed products and excessive washing may irritate sensitive vulval skin.
When it comes to intimate care, more cleansing is not necessarily better.
Vaginal Hygiene: What Should You Actually Clean?
The vagina is the internal canal, while the vulva refers to the external genital area.
Your vagina is self-cleaning and generally does not require internal cleansing. The external vulval area can be gently washed during bathing.
Simple habits that may help reduce irritation include:
- Avoid vaginal douching
- Avoid excessive scrubbing
- Gently pat the area dry after washing
- Choose breathable underwear
- Change out of wet swimwear or sweaty clothing promptly
- Avoid heavily fragranced intimate products
- Stop using a product if it causes burning, itching or irritation
What About Intimate Cleansing Gels?
Some women prefer using a dedicated intimate cleanser rather than regular body wash.
At Healthsprings, TS6 Feminine Cleansing Gel is available as an option for external intimate cleansing.
It is important to remember that an intimate cleanser is a hygiene product. It should not be inserted into the vagina or used for vaginal douching.
It should also not be considered a treatment for:
- Bacterial vaginosis
- Yeast infections
- Sexually transmitted infections
- Urinary tract infections
If you are experiencing persistent itching, burning, unusual discharge, strong odour or pain, repeatedly washing the area is unlikely to address the underlying cause. A medical assessment may be more appropriate.
When Do Changes in Discharge or Odour Need Attention?
Vaginal discharge itself is normal and can change in amount and consistency throughout the menstrual cycle.
However, consider speaking with a doctor if you notice a persistent change from what is normal for you, particularly:
- A strong or fishy odour
- Grey, green or unusually coloured discharge
- Persistent itching or burning
- Vulval swelling or irritation
- Pain during intercourse
- Pelvic pain
- Pain or burning when urinating
- Bleeding unrelated to your period
These symptoms can have several possible causes, including vaginal infections, skin conditions or hormonal changes.
Because different conditions may cause similar symptoms, an intimate wash or over-the-counter product should not replace medical assessment when symptoms persist.
How Perimenopause and Menopause Can Change Vaginal Health
The vaginal environment can begin to change during perimenopause, even before periods stop completely.
As oestrogen levels fluctuate and gradually decline, Lactobacillus levels may decrease and the vaginal environment can become less acidic.
At the same time, vaginal tissue may become:
- Drier
- Thinner
- Less elastic
- Less naturally lubricated
These changes can continue into menopause and may form part of genitourinary syndrome of menopause (GSM).
GSM may involve more than vaginal dryness. Some women experience:
- Vaginal or vulval dryness
- Burning or irritation
- Reduced natural lubrication
- Discomfort during intercourse
- Urinary urgency or discomfort
- Recurrent urinary symptoms
Persistent vaginal dryness should therefore not automatically be interpreted as a hygiene issue or something that requires stronger cleansing.
Could Your Symptoms Be Related to Perimenopause?
Perimenopause can affect more than intimate health.
Some women may also notice:
- Changes in their menstrual cycle
- Hot flushes or night sweats
- Sleep changes
- Mood changes
- Reduced energy
- Difficulty concentrating
Symptoms vary from woman to woman, and having one symptom does not necessarily mean you are in perimenopause.

After Childbirth: It May Not Be a Microbiome Problem
Childbirth can affect intimate health in a different way.
Some women notice:
- Reduced vaginal tissue tone
- A sensation of vaginal laxity
- Pelvic floor weakness
- Urinary leakage when coughing, sneezing or exercising
- Vaginal dryness or discomfort
These symptoms do not necessarily mean that the vaginal microbiome needs to be “corrected”.
Pregnancy, vaginal delivery, changes in pelvic floor support, tissue stretching and hormonal changes can all contribute.
For example, urinary leakage may be more closely related to pelvic floor support, while vaginal laxity may involve changes in tissue elasticity after childbirth.
Where Does Vaginal Rejuvenation Fit In?
For some women, changes in vaginal tissue following childbirth, ageing or hormonal changes may lead them to explore non-surgical vaginal rejuvenation.
At Healthsprings Laser & Aesthetic Clinic, doctor-led options include Er laser and radiofrequency-based treatments for appropriately selected patients.
It is important, however, to separate these treatments from vaginal microbiome care.
Vaginal rejuvenation treatments are not treatments for vaginal infections or microbiome imbalance.
Instead, a doctor first assesses what may be contributing to your symptoms.
For example:
- Vaginal laxity after childbirth may involve tissue elasticity
- Urinary leakage may involve pelvic floor weakness
- Vaginal dryness may be related to hormonal changes
- Unusual discharge or odour may require assessment for infection
- Vaginal changes together with other menopausal symptoms may benefit from a broader menopause consultation
For menopause-related vaginal symptoms, established medical options should also be discussed with your doctor before deciding whether an energy-based treatment is appropriate. Learn More About Vaginal Rejuvenation in Singapore →
When Should You Speak to a Doctor?
Consider a medical assessment if you experience persistent or recurrent:
- Vaginal dryness
- Irritation
- Unusual discharge or odour
- Pain during intercourse
- Urinary symptoms
- Vaginal laxity
- Urinary leakage
- Other intimate changes that concern you
At Healthsprings Laser & Aesthetic Clinic in Singapore, our female doctors provide confidential consultations for women’s intimate health as well as perimenopause and menopause-related concerns.
Depending on your symptoms, your doctor can assess whether the concern may be related to infection, hormonal changes, pelvic floor function or vaginal tissue changes before discussing suitable next steps.
